Letters Patent No. 98,704, dated January 11, 1870.

IMPROVEMENT IN PICKERS FOR WOOL.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'ma/y concern Be it -known that I, STERBEN R. PARKHURST. of Mont Clair, in the county of Essex, and State of New Jersey, have invented, made, and applied to use, a new and useful Improvement in Pickers for Wool, Sto.; and I do hereby declare the following to-be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making p Y part of y this specification, wherein the machine' is represented by a vertical section transversely of the rollers and cylinders.

This invention` relates to a means for feeding into the picker, and thereby mixing with the wool, during the last portions of the picking-operation, the waste from carding-machines, Wool of different grades or color, so that the different qualities are mixed with uniformity, and delivered together. By this means, the loss of ine short fibre is prevented, because the same would be taken away with the refuse matter', if it were supplied with the wool as fed into t-he picker.

This invent-ion is an addition to and improvement upon that forwhch 'Letters Patent were granted to me, July 24, 1866, No. 56,675, and a lreference is hereby made to the construction, operation, and peculiarities of the following parts:

In the drawingais the apron ;v l1 c, the toothed feed-rollers; d, the picker-cylinder; 2, the teeth in the bars l; e, the screen lbelow the picker; f and g are toothed'cylinders, taking the wool from d,- h and i are strippers; k, the receptacle for the motes and'foreign substances; e is a screen vadjacent to the exhaust-trunk m, through which the dust is drawn, by the air, to an exhaustblower; all substantially as in aforesaid patent.

The brush l is not made with bristles, as in the original machines of this character, but I make use of fine steel wires ofthe same length as the bristles, and drawn'in with them into the holes, and secured there- .When the bristles are used alone, the wool or other fibre is rolled up, into loose lumps, upon the cylinders fand g, previously to being thrown o" by the delivery-blast from the blower.

By the use of the steel wires .associated with the bristles, and lying straight with them, the flocks of wool or other tibre are pulled oft the toothed cylinders,

and delivered in an open loose condition,-instead of heilig rolled up.

I apply the feeding-belt 20, for supplying the waste from carding-machines, or other short ibre, and 2l is a toothed roller, carryingthe same up and beneath the curved guard 22, that is hinged, at 23, so that it rests upon and equalizes the batof bre carried into the machine, and the brush-blower Z takes the fibre from the roller 21, and carries it to the Wool` or fibre on the cylinders f y, mixing the samewithsuch fibre in a uniform manner, as the two qualities 'of wool are delivered through the trunk 24.

By this means, the capacity of the picker is increased, a separate carding and mixing-machine dispensed with, and the fibre delivered is in the best condition for future carding and manufacture into fabrics,

the wool being so intimately mixed while in the lightflocular condition.

IVhat I claim, and desire to secure byLetters Patent, is

l. The feeding-belt 2O and toothed roller 21 in com bination .with the delivery-blush and picker, as specified, 'so as-to mix a second quality of Wool into the woolrthat is being delivered from the picker, as set forth. A

2. The delivery-blower I, made with brushes, composed partially ot' straight wires, in combination with the toothed cylinder j or g, for thepurposes and as set forth. A

In witness whereof, I have hereunto ture, this 31st day of May, A. D. 1869.

S. It. PARKHURST.
